Steam Tractor 3/4" (Rudy K)

Thanks Chris,
I don't have much to compare this one to since this is the only displacement lubricator I've ever made.  But it looks like it should work.  That hole's awfully tiny, but that's what Rudy says works, so we're going to give it a try!

Well done on a very intricate little part Kim. Nice pictures as always too!

Yup, the hole does want to be that small. In the inline lubricator style it is usually 3 more drill sizes smaller than yours. Too big and it pumps in to much oil.

Yikes!  I wasn't sure I was going to survive that #72 hole!  Going to something smaller is incredible.  So, did you have to drill a LONG (deep?) hole that small?  I drilled  all the way through a 1/2" length of rod.  Would a small hole in a restrictor plate work equally well?

Oh no, shallow hole. On the cross tube type, the steam tube runs through the top of the oil reservoir, so all you need is a single hole through the top of the tube wall, just the thickness of the tube wall. That acts as the restrictor. In the attached picture the tiny hole is the white bit in the tube, just under the filler cap.

Nicely done Kim!

The next piece was small, which is good, because I didn’t have a lot of time in the shop today.
I made the Steam Pipe which connects the Admission Tee to the Throttle Valve (this will be the next part).

This pipe is a 1/8” brass tube with a flange at each end.

So, first I made the two flanges, just like several before, and cut a length of 1/8” tube.  Here are the parts, posing for a family picture before they’re silver soledered.


And, after a fairly calm session of silver soldering, and some bending, here’s the final product:


The pipe will be bent to the final shape once the pieces are all mounted into place, but this is its approximate shape.

Next up, the Throttle Valve.

OK, no guilt, just interest!
Looking forward to seeing your progress whenever it happens.  The many other facets of life can get in the way of hobbies, can't they?
